UNITED STATES ROBERT A. M. HERMANN, OF NEY YORK, N. Y., ASSIGNOR OF 'IWO-THIRDS PATENT OFFICE.

TO KATIE E. PEOPLE AND WILLIAM JENNINGS, OF SAME PLACE.

MUD-GUARD FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 617,504, dated January 10, 1899.

Application led May 11, 1898. Serial No. 680,395. (No model.)

T0 all whom it may concern:

Be it known that I, ROBERT A. M. HEE- MANN, of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Mud-Guards for mechanism for holding the mud-guard in ex-v tended position and of mechanism forwinding up the apron when not in use.

The frame comprises an extensible bridge 5, connected to bracket 3,which is rigidly secured to the frame of the bicycle by means of the clamps 1, and exten sible bars 4, pivoted to clamps 2 and supporting the outer end of the extensible bridge. Bridge 5 consists of a series of crosswise and endwise pivoted links or braces 14, arranged to operate as a shear. The last pair of braces is connected jointly with the edge 15 of the apron 7 to the hook 13, and thus when the apron is pulled outwardly the bridge supporting it is extended at the same time. Apron 7 is fastened to roller 6 and is wound thereon when the mud-guard is not in use. The rolleris mounted in standards 8, riveted to the bracket 3. A ratchetwheel 9 is set on the axis of the roller 6, and pawl 10 engages with the ratchet-wheel to prevent the unrolling of the apron 7. In winding up the apron roller G is operated by crank 11, and in that case the ratchet-wheel 9 slides on pawl 10.

W'hen extending the mud-guard, the hook 13 is taken hold of with one hand, while the other hand lifts the pawl 10 by pressing on its rear end, and then the apron is pulled out simultaneously. The ends of the rst pair of braces 14 composing the bridge are conresting them when they reach the inward ends of the slots 16. The pins are again disengaged from these catches by pressing the end 2l toward the clamps 1. It will be seen in Fig. 3 that the ends of catches 13 overlap, and therefore by pressing the end 21 toward the clamp 1, as stated above, the end of the other catch will be moved in opposite direction and thereby this catch removed from engagement with the other pin.

Clamps 1 and 2 are secured by screw-bolts 22 to the bars 23 of the bicycle-frame in suitable position. Bars 4: are made extensible to permit the attaching of my improved mudguard to any bicycle regardless of its size.

I claim as my invention and desire to secure by Letters Patent- 1. A foldable mud-guard consisting of a frame, comprising a bracket adapted to be secured to the frame of the bicycle, an extensible bridge having one end pivotally connected to the bracket, extensible bars supporting the other end of the bridge and pivotally mounted in clamps secured to the frame of the bicycle, a roller mounted in standards upon the bracket, an apron secured to the roller and adapted to be Wound thereon and secured with the other end to the extensible bridge, and means for locking the extensible br'idge in extended position and meansl for stretching the apron over the bridge.

2. In combination a bracket adapted to be secured to the frame of a bicycle, a roller mounted upon the bracket, a series of crosswise and endwise joined braces shiftably connected to the bracket by pins secured to the ends of the first pair of the braces and engaging in slots provided in the bracket, catches fulcrumed to the brackets in position to eni IOO e l A 617,504

In witness that I claim the improvements 1o described in the foregoing specification l have signed my name in the presence of two subscribing witnesses.
